The idea is to have 512 pixels in both rows and columns of my image. I'm not sure which function I would use to do so. Any ideas?

Try imresize(). This syntax:
B = imresize(A, [numrows numcols])
should allow you to scale an image without preserving the original aspect ratio.

Thank you! Now I have added a colored image to my workspace, but using colormap(gray) it is still colored. Any ideas?
